3. Principles of Operation
The ultrasonic generator transforms AC line power to a specified signal (rated in kHz)
that drives a piezoelectric converter/ transducer. This electrical signal is converted by
the transducer to a mechanical vibration due to the characteristics of the internal
piezoelectric crystals.
The vibrations are transferred from the piezoelectric converters to the high-grade
stainless-steel tank via the transducers bonded directly to the tank. This vibration is
what powers the ultrasonic cleaning process.
The Vibrations cause small vacuum cavities that are formed. These vacuum cavities
grow with each vibration until they reach a critical point where can no longer hold their
size thus collapsing, or imploding, during compression. This continuing rapid process,
called cavitation, is responsible for the scrubbing effect which produces ultrasonic
cleaning.
